The question of when the COVID-19 pandemic will end is on many people’s minds. Comparisons have been drawn between the Spanish Flu and SARS-CoV-2, the virus responsible for COVID-19. The Spanish Flu lasted from 1918 to 1920 and had four waves. Similarly, nearly two years into the COVID-19 pandemic, we have experienced four waves. So, will it conclude in 2022?
In this article, we will explore potential outcomes for the pandemic’s end, drawing on expert opinions, historical virus patterns, and the latest research and models.
SARS-CoV-2 is a novel coronavirus that carries its genetic information as RNA, distinguishing it from DNA-based viruses. It is an intracellular parasite, meaning it can only reproduce within host cells. While highly infectious, it differs from other RNA viruses like the flu.
To predict the future of SARS-CoV-2, we can examine other coronaviruses that infect humans annually. A recent study analyzed blood samples over several decades for the seasonal coronavirus 229E. The findings revealed that immune markers varied across the 1980s, 1990s, and 2000s, suggesting that coronavirus 229E may mutate over time, leading to reinfections.
The key question is whether SARS-CoV-2 will join the ranks of other coronaviruses that cause mild colds or remain a significant threat. It could become endemic, with infections stabilizing without unexpected spikes, or it could evolve into a more severe illness, akin to a severe flu.
Contrary to the myth that viruses always evolve to become milder, the reality is more complex. Mutations can influence a virus’s transmissibility and its ability to evade the immune system. Early genome sequencing of SARS-CoV-2 revealed accumulating mutations, which can sometimes benefit the virus.
The Delta variant, identified in Spring 2021, was more transmissible than earlier strains due to mutations that enhanced its replication speed. This underscores the importance of vaccination, as unvaccinated individuals are more likely to harbor the virus longer, increasing the chances of mutations.
Omicron emerged with numerous mutations in the spike protein, enabling it to infect previously immune individuals. However, vaccines continue to offer protection against severe disease, and T-cell mediated immunity from mRNA vaccines is crucial in overcoming the pandemic.
Vaccination is essential for creating a barrier of immunity, which can prevent the virus from spreading and mutating further. A globally vaccinated population could lead to higher overall immunity, making it more challenging for the virus to spread and potentially allowing it to become endemic.
Experts consider several scenarios for the future of COVID-19:
The rate at which SARS-CoV-2 evolves will determine how often vaccines need updating. Currently, it is evolving faster than other seasonal coronaviruses, but experts predict it may slow down, potentially requiring updates every year or two.
The strategies employed in the UK and the US, which involve allowing the virus to spread, carry risks and could lead to new strains that evade immunity.
Whether COVID-19 will end this year depends on how we define “end.” We may continue to hear about COVID-19 for years, even if it becomes less severe. The future is in our hands, and it is crucial to vaccinate globally, not just in wealthy nations, to enhance our collective immune response against the virus.
Understanding the complexities of biology, virology, and evolution is key to navigating the pandemic’s future. By staying informed and proactive, we can work towards a safer and healthier world.

When is the COVID pandemic going to end? Many people have been comparing the Spanish Flu to SARS-CoV-2. For example, the Spanish Flu took place over two years, from 1918 to 1920, and consisted of four waves. Here we are, almost two years later, and there have been four waves. So, will it end in 2022?
Today, we’re going to break down how this all might end with specific predictions based on expert opinions, past virus trajectories, and up-to-date research and models.
First off, a reminder that this novel coronavirus carries its genetic information as RNA, not DNA, and is considered an intracellular parasite, meaning it can only reproduce within cells. While SARS-CoV-2 is highly infectious, it is important to understand that it is different from other RNA viruses, such as the flu.
To understand what might happen in the future, it’s worth looking at coronaviruses that infect us each year. A recent study examined blood samples over multiple decades for the seasonal coronavirus 229E. Researchers found that individuals in the 1980s had different immune markers than those in the 1990s and 2000s. This suggests that coronavirus 229E may be mutating over time, which could explain reinfections.
The big question is: when will SARS-CoV-2 join the other four coronaviruses that circulate in populations and cause relatively mild colds? It could become endemic, meaning infections stabilize without unexpected spikes, or it could become more threatening, similar to a severe flu.
It’s a myth that viruses only evolve to become milder. The reality is more complex. Mutations can affect a virus’s transmissibility and its ability to evade the immune response. Early genome sequencing of SARS-CoV-2 showed it was accumulating mutations, which can sometimes be advantageous for the virus.
For example, the Delta variant identified in Spring 2021 was significantly more transmissible than previous strains due to mutations that allowed it to replicate faster. This highlights the importance of vaccination, as unvaccinated individuals are more likely to harbor the virus longer, increasing the chances of mutations.
Omicron emerged with numerous mutations in the spike protein, allowing it to infect individuals who were previously immune. However, vaccines continue to provide protection against severe disease, and T-cell mediated immunity from mRNA vaccines plays a crucial role in overcoming the pandemic.
Vaccination is vital for building a wall of immunity, which can help prevent the virus from spreading and mutating further. If the global population were vaccinated, it could lead to higher overall immunity, making it harder for the virus to spread and potentially allowing it to become endemic.
Experts consider several scenarios for the future of COVID-19:
1. Improved global vaccination leads to increased T-cell immunity, making the virus more likely to become endemic.
2. The virus continues to evolve, requiring annual vaccines to combat waning immunity.
3. A vaccine is developed that offers lifetime protection, with only newborns being susceptible.
4. The virus becomes similar to respiratory syncytial virus, causing mild infections in most children but higher hospitalization rates for infants.
5. It evolves like influenza A, leading to seasonal epidemics driven by adults.
6. It evolves more slowly like influenza B, primarily affecting children.
The speed at which SARS-CoV-2 evolves will influence how often vaccines need to be updated. Currently, it is evolving faster than other seasonal coronaviruses, but experts predict it may slow down, potentially requiring updates every year or two.
The strategies being employed in the UK and the US, which involve allowing the virus to spread, carry risks and could lead to new strains that evade immunity.
So, will it end this year? It depends on how we define “end.” We may continue to hear about COVID-19 for years, even if it becomes less severe. The future is in our hands, and it is crucial to vaccinate globally, not just in wealthy nations, to enhance our collective immune response against the virus.
We hope this video helped clarify the current situation. While it may seem complicated, it ultimately comes down to biology, virology, and evolution. Thank you for watching, and please share this with anyone who might find it helpful. We’ll see you next week for a new science video!
